Description

KODAK HAWKEYE Traffic Surveillance Color Film is a 400 speed color negative film for traffic surveillance applications. KODAK T-GRAIN emulsion technology provides extremely fine grain and high sharpness, and wide exposure latitude allows a range of exposures from 2 stops under to 3 stops over normal. Other features include:

• Improved color saturation; accurate colors
• Push performance to EI 800
• Optimized for use with film scanners; durable emulsion overcoat prevents scratches
• Panchromatic sensitivity to 660 nm
• Balanced for daylight or electronic flash, and may also be used under mixed lighting
• Prints compatibly with KODAK GOLD and MAX Versatility Films
• Process using KODAK FLEXICOLOR Chemicals, Process C-41
• Coated on a 0.0048-inch (0.12 mm) acetate base

Darkroom Recommendations

Handle unprocessed film in total darkness—do not use a safelight.

Process this film in total darkness through the bleach step in Process C-41.

Storage and Handling

Load and unload film in subdued light.

Store unexposed film at 70°F (21°C) or lower in the original sealed package. Process film as soon as possible after exposure. Protect negatives from strong light. For more information about storing negatives, see KODAK Publication No. E-30, Storage and Care of KODAK Photographic Materials—Before and After Processing.

Exposure

Speed:

Use these speed numbers with meters and cameras marked for ISO, ASA, or DIN speeds or exposure indexes. For critical work, make a series of test exposures.

Daylight Exposure:

Use the exposures in the table below for average frontlit subjects from 2 hours after sunrise to 2 hours before sunset when exposing at EI 400.

Electronic Flash:

Use the guide numbers in the table below as starting-point recommendations for your equipment. To determine the lens opening, divide the guide number by the flash-to-subject distance.

Filters

For light sources other than daylight, use the filtration and exposure compensation in the table below.

Note: Do not change the film speed setting when metering through a filter. Metering through filters may affect light meter accuracy; see the meter manual (or camera manual for built-in meters) for specific information.

Fluorescent and High Intensity Discharge Light:

Though this film is tolerant of mixed-lighting situations, for best color results under uniform fluorescent or high-intensity discharge sources, use the exposure and filter recommendations given below. These recommendations are starting points.

Actual filtration may vary between lamps and lamp manufacturers. Depending on the specific source, additional filtration or special printing may be required to achieve best results.

To avoid the brightness and color variations that occur during a single alternating-current cycle, use exposure times of 1/60 second or longer with fluorescent lamps; with high-intensity lamps, use exposure times of 1/125 second or longer.

Reciprocity

Compensation for reciprocity failure is not necessary for exposures of 1/10,000 second to 10 seconds. Exposures longer than 10 seconds may require exposure compensation and/or filtration, and should be tested for the application.

Processing

Normal Processing:

Use KODAK FLEXICOLOR Chemicals, Process C-41, in any processing equipment designed to accommodate Process C-41.

Push Processing:

This film may be "pushed" 1 stop by exposing at EI 800, and extending the development time in Process C-41. (This time increase may not be possible in all processing equipment.)

Judging Negative Exposures

Expose this film properly for best results.

Check the exposure level of the color negative with a suitable electronic densitometer equipped with a filter such as the red filter for Status M Densitometry, or a KODAK WRATTEN Gelatin Filter No. 92. Depending on the subject and the light source used for exposure, a normally exposed color negative measured through the red filter should have the approximate densities listed below. These densities apply for the recommended light sources and correct processing of the negative.

Densities of Properly Exposed and Processed Negatives:

Expose this film properly for optimum results.

Check the exposure level of the color negative with a suitable electronic densitometer equipped with a filter such as the red filter for Status M Densitometry, or a KODAK WRATTEN Gelatin Filter No. 92. Depending on the subject and the light source used for exposure, a normally exposed color negative measured through the red filter should have the approximate densities listed below. These densities apply for the recommended light sources and correct processing of the negative.

Scanning Negatives

General

Traffic Surveillance Color Film negatives can be easily scanned with a variety of photomultiplier tube (PMT), linear-array charge-coupled device (CCD) and area-array CCD scanners. The film can be scanned using desktop as well as higher-end drum or flat-bed scanners. Since there is no established standard for filter sets used in film scanners, each manufacturer's scanner will have its own characteristic output. The sensitivity of a scanner to a film's dye set is determined by the spectral sensitivity of the CCD and the spectral distribution of the colored filters used to capture the red, green and blue information contained in the film. A scanner's characteristic output may also be affected by the look-up tables or matrices used by the scanner to output information for monitors, transmission, etc. These tables or matrices can be in the form of a "plug-in" program used with a specific image manipulation software package, updateable ROMs included with the equipment, or fixed algorithms for determining calibration and balancing, similar to those used in photographic color printing equipment.

The generic "color negative film" channel designation available with scanner software will provide only a starting point for balancing. The final color balancing and adjustment of scene-dependent contrast and brightness for any particular image can be done using scanner controls at the pre-scan stage, or after the image is imported through the imaging software or workstation.

Some scanners allow for the use of "plug-in" programs that will calibrate on D-min film stock. Since every color negative film has a different colored-coupler mask, the optimum D-min balance will be different for each film. Therefore, optimum scanning of these films are accomplished through the use of specifically calibrated channels.

KODAK Photo CD Imaging Workstation (PIW)

Photo CD Film Term tables store information that determines the tone scale and color reproduction characteristics of a Photo CD image. These tables also contain photographic information about different types of film, and parameters specific to each film.

Photo CD Film Term tables are intended for use by owners and operators of KODAK Photo CD Imaging Workstations (PIWs), and can be downloaded from Kodak's website.

Printing Negatives

This film is optimized for printing on KODAK EKTACOLOR Edge 8, KODAK ROYAL VIII, KODAK EKTACOLOR Edge 9, and KODAK ROYAL IX Papers. The film can also be printed on KODAK PROFESSIONAL DURAFLEX Plus Digital Display Material.

Make color slides and transparencies by printing the negatives on KODAK PROFESSIONAL ENDURA Transparency Optical Display Material or KODAK PROFESSIONAL ENDURA Clear Optical Display Material.

Make black-and-white prints on KODAK PANALURE SELECT RC Paper for conventional black-and-white processing, or KODAK PROFESSIONAL PORTRA Black & White Paper for Process RA-4.

Retouching

Retouch only the emulsion side; apply KODAK Retouching Fluid before using KODAK Retouching Pencils.

For information on retouching equipment, supplies, and techniques, see KODAK Publication No. E-71, Retouching Color Negatives.

Print Size in inches:	4x6	8x10	16x20
Print Size in centimeters:	10.2x15.2	20.3x25.4	40.6x50.8

Print Grain Index number:	39	61	90

• This is a new method which replaces rms granularity. It is on a different scale, which cannot be compared to rms granularity.
• The scale is a uniform perceptual scale, with a change of 4 units representing a Just Noticeable Difference for 90% of observers.
• Index value representing the approximate visual threshold for graininess: 25.
• Standardized inspection distance for all print sizes: 35.6 cm (14 inches).
• In practice, prints larger than 10.2 x 15.2 cm (4x6 inches) will likely be viewed from distances greater than 35.6 cm (14 inches), thereby reducing overall graininess that is perceived.
• These Grain Index numbers may not represent graininess observed from more specular printing illuminants, such as condenser enlargers.
